Warranty, support and FAQs
Connect the fan to the motherboard’s CPU fan header.
Depending on your CPU and the temperature inside the
case, you may interconnect the supplied NA-RC7 Low-Noise
Adaptor (L.N.A.) in order to further reduce the fan’s operating
noise.
Caution: When using the L.N.A., check the temperature of
your CPU using appropriate software (e.g. the respective
applications of your motherboard manufacturer), in order to
evade automatic throttling of the CPU due to the increased
temperature. If the cooling performance is insufficient, please
increase case ventilation or remove the L.N.A..
Adding a second fan
The NH-U9S chromax.black includes an extra set of fan clips
for installing a second NF-A9 fan in push/pull mode in order
to further improve cooling performance.
